Krell Industries S1500 manual Definition of Terms

Definition of Terms

	Following are the definitions of key terms used in this owner’s ref-
	erence.
INPUT AND OUTPUT	Balanced
CONNECTIONS	A symmetrical input or output circuit that has equal impedance
	from both input terminals to a common ground reference point.
	The industry standard for professional and sound recording instal-
	lations, balanced connections have 6 dB more gain than single-
	ended connections, and allow the use of long interconnect cables.
	Balanced connections are less susceptible than single-ended con-
	nections to induced noise from the system or the environment.
	Single-ended
	A two-wire input or output circuit. Use care when using single-
	ended connections as the ground connection is made last and
	broken first. Turn the system off prior to making or breaking single-
	ended connections. Single-ended connections are not recom-
	mended for connections requiring long cable runs.
OPERATION	Off
	When the AC power cord is not plugged into the wall, the front
	panel LED is not illuminated and the component is off.
	Stand-by Mode
	When the AC power cord is plugged into the wall, the front panel
	stand-by and power LED (2) illuminates red, indicating that the
	component is in the stand-by mode. This low power consumption
	status keeps the audio and circuits at idle. Krell recommends leav-
	ing the component in the stand-by mode when it is not playing
	music.
	Operational Mode
	From the stand-by mode, when the power button on the front
	panel is pressed and the front panel stand-by and power LED (2)
	illuminates blue, the component is in the operational mode and
	ready to play music.
TECHNOLOGY	Krell Current Mode
	A proprietary Krell circuit topology in which the audio gain stages
	of a component operate in the current domain, rather than the
	voltage domain. This unique technology provides the component
	with exceptional speed and a wide bandwidth.
